Pneumatic Products, eSafe Couplings & Nipples

Series 300 eSafe, DN 5.5

  • Vented safety function
  • High flow capacity
  • Strong and durable


Series 300 eSafe couplings offer high flow and require only a low connection force, which ensures a safe working environment. eSafe is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. Male threads on the couplings and nipples feature pre-applied thread sealant. A fully automatic operation ensures quick and easy handling. eSafe complies with ISO Standard 4414 and EN 983.


Series 300 is also available in Soft-Line and Multi-Link versions.
